Abstract

The invention discloses a cultivation method increasing the content of effective components of rhodiola crenulata, and belongs to the technical field of rhodiola cultivation. The method comprises the following steps that in the budding time of the rhodiola crenulata, base fertilizer is applied; in the fruit period of the rhodiola crenulata, fertilizer is additionally applied, wherein the base fertilizer and the additional fertilizer are nitrogenous fertilizer, phosphatic fertilizer and potash fertilizer, the applying amount of the nitrogenous fertilizer is 45%-50% of the soil weight percent, the applying amount of the phosphatic fertilizer is 10%-15% of the soil weight percent, and the applying amount of the potash fertilizer is 55%-65% of the soil weight percent. According to the method, the content of the effective components of the rhodiola crenulata can be effectively increased, the content of salidroside in the rhodiola crenulata is increased by 5%-8%, the content of butyl alcohol in the rhodiola crenulata is increased by 20%-25%, and the content of gallate in the rhodiola crenulata is increased by 40%-45%.

Description

technical field [0001] The invention relates to a cultivation method for increasing the content of effective components of Rhodiola daflora and belongs to the technical field of Rhodiola rosea cultivation. Background technique [0002] Rhodiola crenulate (Hook.f.et Thoms.) H.Ohba] is a plant of the genus Rhodiola (Rhodiola L.) of Crassulaceae (Crassulaceae), and has the reputation of "plateau ginseng". The 2010 edition of "China Pharmacopoeia included Rhodiola rosea (R.crenulate) as the only medicinal variety of Rhodiola rosea. Rhodiola daflora mainly contains salidroside, tyrosol, pyrocombic acid, gallic acid, rhodiola rhodiola and other ingredients; it has anti-aging, anti-hypoxia, anti-fatigue and other effects. Rhodiola daflora in my country is mainly distributed in Tibet, Sichuan, Yunnan and other western regions, and has high development and utilization value. In recent years, due to the excessive development and utilization of Rhodiola rosea resources, coupled with ...
